These are large, brightly colored, calendar pieces to be used for math in Kindergarten, 1st, or 2nd grade. They are designed based on Common Core Standards. Students may practice reading a clock, creating groups of coins for a given amount of money, and various counting strategies for tens and ones including counting on, counting by 5's and 10's and doubles. This spiraling of Common Core Standards will increase student knowledge of mathematics and its vocabulary. Look for more by Nelson Bonn.
